The site's time is "wrong" - how do I change it to my correct time zone?

All site times are automatically set to Greenwich Mean Time (GMT). You can adjust this in the User Control Panel ('User C/P', which is the second link on the main portal bar at the top of every page). Click on the 'Edit Options' section of 'Settings & Options' (in the left hand column) and scroll down to 'Date & Time Options'. There, you can change your time zone to the correct one; Daylight Savings Time (DST) adjustments can also be made here.
